# ESD5V0B03-1006

**TECH PUBLIC** · ESD Protection Devices · DFN1006-2

ESD5V0B03-1006 from TECH PUBLIC, in a DFN1006-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Terminal 1 of the bidirectional TVS diode, shown at the top of the terminal diagram, with reverse working voltage 5 V max and 0.3 pF typical junction capacitance (IO to IO, VR = 0 V, f = 1 MHz). |
| 2 | 2 | passive | Terminal 2 of the bidirectional TVS diode, shown at the bottom of the terminal diagram, with the same ratings as pin 1 since the device is bidirectional (breakdown 5.8 V min to 9 V max at IT = 1 mA). |
